SMOKING PIPE Filed Oct. 9, 1931 INVENTOR Patented Feb. 14, 1933 UNITEDSTATES JOHN P. MARTIN, OF PITTSBURGH, PENNSYLVANIA SMOKING PIPEApplication filed October 9, 1931. Serial N0. 567,803.

This invention relates to smoking appliances, particularly tobaccopipes, but may also he applied to other types of smoking tubes such ascigar holders and cigarette holders. I

According to my invention, I provide a bit or mouthpiece that preventsor retards saliva from the mouth of the smoker, entering the smokepassage of the stem, also to prevent or retard condensate that maycollect in the smoke passage 01": the stem from being drawn into themouth of the smoker.

The invention provides, moreover, a stem of unique shape which will givethe smoke passage of large cross section in a given stem and at the sametime provide a wide flattened surface at the bit end, which stem willhave a pleasing and serviceable contour. In addltion, the inventionprovides a bit that will discharge smoke laterally and far removed fromtip of tongue. Such construction in conjunction with the wide flattenedsurface of stem make it most unlikely that the smoker will have a soretongue from the use of the pipe.

By providing a stem having the large size of smoke passage a coolingeffect on the smoke is obtained by the fact of the smoke mixing with amuch larger body of air within the smoke passage and also by coming incontact with a larger area of smoke passage wall, than in the ordinarystem.

The ordinary smoking pipe is so constructed that the smoke is dischargedinto the mouth always at practically the same location notwithstandingthe fact that the pipe may be moved from one side of the mouth to theother. The point of discharge is usually closely adjacent the tip oftongue. and the continued impingement of the smoke at this point plusthe seepage from stem cause an irritation of the tip of the tongue.Moreover, the ordinary stem as now generally made, has a straight bit. Aperson having natural teeth finds no difiiculty in retaining bitin themouth, but a person whose teeth have been removed or who is usingartificial teeth has considerable dificulty in getting a sufiicient biteon the stem to permit the pipe to be held in the mouth unsupported bythe hand.

A further disadvantage of the present day stem is the fact that thestraight open end of smoke passage permits the flow of saliva into saidpassage Where it absorbs a condensible material from the smoke,resulting in the accumulation of a mass within the stem that partiallyor wholly stops the very small smoke passage after which it is drawninto the mouth of smoker, discharging on to the tip of the tonguecausing what is frequently called a burned tongue.

Pipes have been devised having traps between the stem and the bowl forthe collection of condensate and saliva, but such pipes do not preventthe entrance of saliva from the mouth into the stem, andlt is thissaliva from the mouth that causes most of the trouble.

According to the present invention there is provided a smoking appliancehaving a bit so constructed that the smoke is discharged into the mouthcavity laterally instead of against the tip of the tongue, so that nolrritation is produced from this source. The bit is so constructed thatthe pipe may be readily retained in the mouth unsupported by the hand bya person having artificial teeth or having no teeth, and be morecomsible smoke passage in a glven stem, makes it practically impossiblefor any saliva to enter the smoke passage of stem, or any condensatefrom smoke passage to be drawn into the mouth of smoker.

To secure the best practical results, I have so designed the stem shapeand dimensions that it will admit of. the largest smoke passage possiblein a given size stem, while at the same time it will present apleasingcontour, and a wide flattened surface close to smokepassage has: rarelyto be cleaned as ni 7 a a I .e a V -F1gure 2 lea slde y1ew"0f mynnproVed bit portion where teeth or gums engage stem tokeep stem fromrotating. Also the large area of smoke passage hasa decided tendency to:cool the smoke because itimixes with the large body of air in smokepassage and also comes in contact with the much larger area of the wallsof the, stemf Also the large nothing but condensate enters"it, whichcondensate in the absence of saliyaislvery little- The invention may bereadily i understood ,by reference tothe accompanying drawing in which:
